HPLC Syringe Filter Supplier

Due to the high hydrophobicity of the PVDF membrane, it needs to be soaked in an appropriate solution such as ethanol before use to achieve the purpose of activation and make the membrane easier to bind proteins. This product is compatible with many dyes, such as Ponceau-S red, Coomassie brilliantblue, Sypro ruby, Transillumination, Toluidine blue, CPTS, Colloidal gold, India inkAmido black. Among them, after dyeing with dyes such as Ponceau and CPTS, the dyes can be washed off and the film can be used for further analysis; while dyes such as Coomassie Brilliant Blue, India ink, and amide black are irreversible, the film cannot be used after dyeing. For further analysis.

In HPLC analysis, the particle size of the chromatographic column packing is small and easily blocked by contaminant particles. t. In HPLC analysis and IC analysis, syringe filters can be used to filter sample solutions, which is an important step in sample pretreatment.

Hydrophilic PTFE syringe filters offer a choice for aqueous samples that are diluted with harsh chemicals. These filters can handle high-temperature liquids, excellent flow rates, low protein binding, and are compatible with most bases, acids and organic solvents.

In order to filter the particles correctly, you need to find the right size filter. You should choose the diameter of the filter carefully. They usually have sizes of 13mm, 25mm and 30mm. Each of these has a different ability to hold particles. According to the sample size, you can choose the appropriate filter diameter. For example, a diameter of 13 mm can be used for 1-10 ml samples. Similarly, 25 mm PVDF syringe filters can be used for sample volumes of 10-100 ml. Their retention is less than 100 ml.

Syringe filtration is a crucial technique in laboratory settings, playing a vital role in sample preparation for various analytical methods.

The PTFE Syringe Filter in the picture has an aperture of 0.22, an outer diameter of 25mm, and a purple color. Aijiren also offers many other colors of Syringe Filter, such as yellow, pink, blue, green, etc. Customers can choose according to their preferences . The Syringe Filter produced by Aijiren can be equipped with many different types of filter membranes, which can be selected according to the reagents that customers need to filter.

In chromatographic experiments, the sample is placed on the chromatographic column for analysis after the sampler is injected. However, the inner core of the sampler and the chromatographic column is relatively thin. If there are large particles in the sample, it may cause the device to block , Need to use Syringe Filter for preliminary sample filtration treatment.

The syringe filter produced by Aijiren is the preferred method for filtering small samples before being loaded into HPLC and GC, and is usually used with disposable syringes to filter out impurities in the sample to ensure that there is no quality in the test Problems and affect the experimental results.

syringe filter is a small, disposable filter device that is commonly used in laboratory settings for the filtration of liquids. It is designed to be attached to a syringe, allowing the liquid to be passed through the filter membrane under pressure.

Syringe Filters with hydrophobic PTFE membranes can be used for filtration of strong solvents, acids and alkalis. Not suitable for filtration of aqueous liquids. Filters with hydrophilic PTFE can be used for filtration of strong solvents, acids and alkalis. However, these syringe filters can also be used for the filtration of aqueous liquids, which makes this type very versatile.

The Sterile syringe filter produced by Aijiren is a single-use membrane-based filtration facility that is mostly used to remove particulate impurities from liquid and gas samples before analysis by HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing methods. . Correctly filtering samples in chromatographic experiments can improve the quality and consistency of analysis results and reduce instrument downtime. The sterile syringe filter adopts high-temperature aseptic processing and vacuum packaging of liquid to ensure the cleanliness of the syringe filter. It is recommended to be used once.

Aijiren disposable MCE syringe filter units are designed to provide clear filtration of aqueous and organic solutions from small volumes up to 100 mL.
MCE syringe filters are made from mixed cellulose ester (MCE) membrane and polypropylene overmolded housing.

Disposable syringe filter devices are designed to provide fast and efficient filtration, premium quality and economy. The membrane could be PTEF, PVDF, PES, Nylon, MES, PP, CA, and can be suitable for different situations.

PES syringe filter is mainly used for filtering and sterilizing liquid samples of small volume samples such as a small amount of buffers, protein solutions, additives, various reagents or drugs, and removing particles. It is also the first choice for sterilization and filtration of small samples of HPLC and GC. method.

This nylon membrane can be used for alkaline blotting and fixation, but if fixing methods such as baking and ultraviolet rays are used, higher nucleic acid detection sensitivity can be obtained. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in ethanol, methanol and other solutions for activation. This product is only for scientific research by professionals, and must not be used for clinical diagnosis or treatment, or used for food or medicine, and must not be stored in ordinary residences. For your safety and health, please wear lab coats and disposable gloves for operation.

Aijiren’s syringe filters with nylon membranes are compatible with a wide range of solvents, making them ideal for fast filtration of most aqueous and organic solutions. Therefore, when a mixture of sample aqueous solution and organic solvent passes through nylon membrane, fine droplets of extractor solvent accumulate and are separated from the sample aqueous solution. Using this simple method, the total extraction time is only 3-4 minutes; It is environmentally friendly, has no centrifugal effect, provides a higher sample purification rate by filtering receptor phases, and filtering reagents ensures reduced impurities and protects the color column.

Unique raised column structure with 0.45μm PES membrane processes double sample volume vs conventional filters, extending service life.

A syringe filter is a quick, convenient and reliable filter tool used routinely in the laboratory. Because they don’t need to change the membrane and filter cleaning, it’s eliminating the complex and time-consuming preparation.  

Among the many medium types of Syringe Filters produced by Aijiren, Polypropylene Syringe Filter is a special one. Because Polypropylene is often used to make the shell of Syringe Filter, there are fewer types of membranes made of Polypropylene. Aijiren finally decided to use this material to produce Syringe Filter after studying the production materials of many different manufacturers and the usage of different customers.

Polypropylene (PP) is recommended for one time use only with low vapor transmission. Polypropylene is a rigid plastic that is translucent. At room temperature, polypropylene exhibits excellent chemical resistance to acids, alcohols, and bases. Polypropylene is compatible with acetone, ethyl acetate, methanol, isobutyl alcohol, methanol, and methyl ethyl ketone. Polypropylene is incompatible with cyclohexane, ethers, dichlorobenzene, pentanes, methylene chloride, and trichlorobenzene.
